MOBILE DX
MASTER Since its introduction over a year ago, Yaesu's FT-100
HF/VHF/UHF Transceiver has been widely acclaimed for its outstanding
performance and flexibility. Now the FT-100D builds on this success story,
adding the convenience of factory-installed modules for today's Ham on the
go!

WIDE
FREQUENCY COVERAGE!The FT-100D is the smallest transceiver in the
world providing such wide frequency coverage. Providing transceive
coverage of the HF, 50 MHz, 144 MHz, and 430 MHz amateur bands on SSB, CW,
AM, FM, AFSK Teletype, and Packet, the MICRO MOBILE also includes receive
coverage of 100 kHz through 961 MHz (cellular and digital telephone
frequencies are blocked), so you can monitor public safety, weather
broadcast, AM and FM broadcast, and TV audio transmissions, in addition to
all the action on the ham bands. All this from a rugged compact case
measuring just 6.3" (W) x 2.2" (H) x 8.0" (D) (160 x 54 x 205 mm).

HIGH-PERFORMANCE RECEIVER DESIGN! Building on the
acclaimed performance of the FT-1000D, FT-1000MP, and FT-847, Yaesu's
engineers have crafted the FT-100D's front end for a very low noise floor
and wide dynamic range. Utilizing an up-conversion architecture for HF
with a 68.985 MHz first IF, the FT-100D features a double-conversion
superheterodyne system (triple-conversion on FM) with the 2nd IF at 11.705
MHz. The first mixer is a low-noise, high-intercept design using SST310
JFETs in a doubly-balanced configuration. On 144/430 MHz, the
very-low-noise GaAs MES FET SGM2016 preamplifier is followed by an HSB88
diode-ring mixer, yielding the excellent Noise Figure required for
weak-signal work. The front-end devices are individually selected and
matched, ensuring a high level of performance consistency as units are
manufactured.

ENHANCED
TRANSCEIVER PERFORMANCE THROUGH DIGITAL SIGNAL PROCESSING! For
superior interference rejection and transmitter "talk power," the
FT-100D's DSP circuitry enhances both sides of the communications circuit.
The FT-100D's DSP Unit features a 24-bit high-tech D/A chip for signal
processing. •Digital Dual Bandpass Filter : Providing "brick wall" audio
selectivity for voice modes, the Bandpass filter allows independent
High-Pass and Low-Pass Filter adjustments, with cutoff frequencies of 100
Hz ~ 1000 Hz (HPF) and 1000 Hz ~ 6000 Hz (LPF). On CW, the Bandpass filter
becomes an Audio Peaking Filter with available bandwidths of 60/120/240
Hz. •Noise Reduction Filter : Building on the highly-successful Noise
Reduction feature of the FT-920, the FT-100D's DSP utilizes
multi-parameter analysis for efficient processing and reduction of
incoming noise. A total of 16 Noise Reduction settings are available for
best results under changing conditions. •Automatic Seeking Notch Filter :
For removal of annoying carriers or heterodynes, the DSP Notch Filter will
identify and suppress one or more such signals automatically, thus
improving copy and reducing operator fatigue. •Microphone Equalizer : To
match the FT-100D's transmitter audio response to the waveform produced by
your voice and the microphone in use, the DSP system includes a
three-position Mic Equalizer circuit. The result is increased "talk power"
as extraneous frequencies are suppressed, allowing all available power to
be concentrated into your voice's pattern.

DIRECT
DIGITAL SYNTHESIZER! To ensure the dual goals of low receiver
noise floor and wide dynamic range, Yaesu's engineers utilize an AD9850
Direct Digital Synthesizer (DDS) for the main local oscillator of the
FT-100D. Providing fast lock time and excellent Carrier-to-Noise (C/N)
ratio, the DDS also yields tuning steps as small as 1.25 Hz, for
silky-smooth action indistinguishable from an analog VFO system. The PLL
circuits in the FT-100D feature a low-noise custom J-FET device (FQ7925),
thus enhancing system performance.

ADVANCED
FEATURES FOR ACTIVE DXERS!•IF Shift : Use the IF SHIFT feature to
vary the center frequency of the IF passband, so as to eliminate
interference above or below the current operating frequency. •IF Noise
Blanker : Optimized for use in the mobile environment, the FT-100D
includes an effective IF Noise Blanker specially designed for suppression
of ignition and other pulse-type noises. The Noise Blanker's threshold is
adjustable via the MENU system. •Intercept Point Optimization (IPO) :
For reception on the lower frequencies, where very low Noise Figure is not
required, the IPO feature causes the RF preamplifier to be bypassed,
allowing direct signal input to the first mixer. An input attenuator is
also available, for reception under extremely noisy conditions.
•Adjustable AGC : The Automatic Gain Control (AGC) circuitry of the
FT-100D's receiver may be adjusted, via the MENU, for SLOW or FAST
receiver recovery times. A convenient "AUTO" setting programs "FAST" AGC
for CW, and "SLOW" for voice modes. •Clarifier (RIT) : For
split-frequency pile-ups or to follow drifting signals, the Clarifier
control provides up to ±9.99 kHz of adjustment of the receiver's
frequency, without changing the transmitter frequency. For wider-split
pile-ups, the "SPLIT" mode allows you to use VFO-A and VFO-B separately,
too. •RF Gain Control : For noise reduction and/or variation of the
AGC system threshold, the MENU allows the front panel's Squelch control to
be switched to operate as an "RF Gain" control. •VOX : For hands-free
voice operation, the VOX system includes MENU adjustments for both VOX
Gain and Delay. A separate setting is also provided for receiver recovery
in the CW mode. CW OPERATING FLEXIBILITY! •Built-In Electronic Keyer :
The FT-100D's built-in Electronic Keyer includes Dot : Space and Dash :
Space weight adjustments. •CW Message Memory : For repetitive "CQ DX"
or "CQ TEST" messages, the FT-100D includes a 50-character CW Message
register.•CW Full Break-In (QSK) : Both "Full QSK" and "Semi-Break-In" CW
modes are available, with excellent keyed waveforms in both modes. •CW
"Reverse" Reception : When interference is encountered in the CW mode, the
"Reverse" feature allows the injection sideband to be changed between
"USB" and "LSB" by a simple press of the "MODE" switch on the front panel.
•CW Pitch/Sidetone Control : The CW PITCH control allows the
transmitted signal to be offset 400/500/600/700/800 Hz from "zero beat"
with the receive frequency. This adjustment simultaneously varies the
center frequency of the RX passband (including the DSP BPF), as well as
the CW Sidetone's pitch. The sidetone therefore serves as a "Spot" signal
during tuning. •Optional Narrow Filter: The ultra-narrow XF-117CN 300
Hz CW filter is an available option for the FT-100D, providing an
additional CW filter selection for use during very crowded conditions.

MULTI-FUNCTION "SELECT" KNOBThe front panel's SELECT
knob acts as a Quick-QSY dial for tuning, with independent steps on
different bands and modes. The SELECT knob is also used for Memory Channel
and MENU item selection, as well as CLARIFIER tuning and IF SHIFT
adjustment.

ONE-TOUCH
SCROLLING FRONT PANEL The A, B, C, and D keys below the display
provide access to many control functions for the FT-100D, including VFO
selection, Memory Channel loading, Repeater Shifts and Tones, and Filter
selection . See the chart below.

MULTI-PURPOSE MEMORY SYSTEM!The FT-100D provides 6
Memory Groups of 50 Channels each, for a total of 300 "Regular" memories.
In addition, you get 20 "Split Frequency" memories, 5 Quick Memory Bank
(QMB) memories, 4 "Home" Channel memories, and 20 Band-Limit memories, for
a grand total of 349 Memory Channels! Use the QMB or Home channels for
Quick QSY to a favorite frequency, and use the Split memories for
DX-pedition pileups or 7 MHz SSB work.

VERSATILE
SCANNING MODES! •VFO Scan : Scan up or down the band in the VFO
mode. •Memory Scan : Scan within the current Memory Group, or scan all
the memories. •Programmable Memory Scan (PMS) : Use PMS to scan within
band limits set by the special PMS memories. •QMB Scan : When
operating on the QMB channels, you can also elect to scan just those
memories. During scanning operation, the FT-100D can be set up to Stop
completely when a signal is encountered; to Hold until the incoming
transmission ceases; or to Resume after a delay of 1 to 10 seconds.

HIGH-RESOLUTION DOT-MATRIX DISPLAY!The large (70 mm x
30 mm) blue LCD dot-matrix display provides easy-to-read indication of
many operating functions, including frequency, RX and TX metering,
operating functions, status icons, and the Spectrum Scope bar-graph. And
to set the illumination level precisely to the brightness you want, the
MENU provides a "Dimmer" feature with 64 degrees of illumination.

OPTIONAL
REMOTE MOUNTING KIT! For mobile operation where mounting space is
very limited, the optional YSK-100 Separation Kit allows the front panel
to be remotely mounted on your dashboard, with the transceiver stashed
away in available space. Data is transferred between units at a
lightning-fast rate of 62,500 bps, for seamless remote operation.

LEADING-EDGE FEATURES FOR VHF/UHF OPERATORS!•Automatic
Repeater Shift : On the 144 MHz and 430 MHz bands, the FT-100D will
automatically activate the repeater shift appropriate for the part of the
band in which you are working. •CTCSS/DCS Tone Systems : For repeater
access, a CTCSS Encoder/Decoder is built into the FT-100D, and for
advanced repeater systems a 104-code Digital Code Squelch system provides
improved immunity from false decoding.

•Smart
Search™ : When visiting a new city, use the Smart Search™ system to scan
the FM band for activity. When busy channels are found, they will be
automatically loaded into a special Smart Search™ Memory Bank, for easy
recall.

•Spectrum
Scope : If you have to be away from your radio for a few minutes, turn on
the Spectrum Scope to keep watch on band activity. The Spectrum Scope will
create a bar-graph display of activity on 15 channels above and below your
current operating frequency. •ARTS™ (Auto-Range Transponder System) :
During Search-and-Rescue operations, the ARTS™ feature will notify you if
a field station (for example, a hand-held unit) has gone out of
communications range, so you can instruct them to move to a better
location.
